this will get the value of the first selected cell.

dataGridView1.SelectedCells[0].Value

You're on the right track. SelectedCells is a collection of cells that have been selected by the user (even if only one has been selected, it is still a collection). To get to the selected cell, assume it is the first cell in the collection (it will be). You then have to get its value as a string.

In short, your answer is:

label1.Text = dataGridView1.SelectedCells[0].Value.ToString();

Let's take this a step further. Let's say you want to pass multiple values of the row cells selected and
process or send these values to the next screen. First set the SelectionMode property of the DataGridView = FullRowSelect.
This will highlight (select) the entire row, then since you know the order of the columns on the grid, use the following code
which is initiated upon the user clicks (selects) the grid row.

 private void gridColors_CellContentClick(object sender, DataGridViewCellEventArgs e)
		{		   
			string CustId = gridColors.SelectedCells[0].Value.ToString();
			string CompName = gridColors.SelectedCells[1].Value.ToString();
			string ContName = gridColors.SelectedCells[2].Value.ToString();
			string ContTitle = gridColors.SelectedCells[3].Value.ToString();
			string Address = gridColors.SelectedCells[4].Value.ToString();
			string City = gridColors.SelectedCells[5].Value.ToString();
			string Region = gridColors.SelectedCells[6].Value.ToString();
			string ZipCode = gridColors.SelectedCells[7].Value.ToString();
			string Country = gridColors.SelectedCells[8].Value.ToString();
			string PhoneNbr = gridColors.SelectedCells[9].Value.ToString();
			string FaxNbr = gridColors.SelectedCells[10].Value.ToString();

			frmChild newfrmChild = new frmChild(CustId, CompName, ContName, ContTitle, Address, City, Region, ZipCode, Country, PhoneNbr, FaxNbr);
			newfrmChild.ShowDialog();
			newfrmChild.Dispose();

I am having a problem with the same.. Following is my code..

[code] datagrid1.SelectedCell[0].Value.ToString() </code>

Whenever I run the program it throws me the following exception:

System.NullReferenceException: Object reference not set to an instance of an object.
at WindowsFormsApplication1.frmPOS.Control_KeyPressData(Object sender, KeyPressEventArgs e) in C:\Users\Zishan Haider\Documents\Visual Studio 2010\Projects\WindowsFormsApplication1\WindowsFormsApplication1\frmPOS.cs:line 106

It seems to me that Value property is not referenced. I am using Visual Studio 2010 beta II. Can anyone help me with that??
